Incongruent Freshwater Lenses Of The River Murray Floodplains (Australia): Discovery Of A New Groundwater Phenomenon In Dry Riparian Zones

Groundwater hydrology is a mature research field. The idea of discovering a new type of groundwater system seems unlikely. Yet, in the floodplains of the River Murray system, freshwater lenses float on saline groundwater under conditions that seem, on first impression, counterintuitive and unfavorable for the persistence of fresh groundwater. In this research, a new type of fresh groundwater system is discovered in the form of buoyant freshwater lenses opposing both the river-bound flow of saline groundwater and the density...

Freshwater Beneath The Sea: Investigating A Hidden Resource

Groundwater beneath the seafloor in many of the world’s continental shelves has salinities well below that of seawater. Increasingly, there is pressure to tap into these subsea freshwater reserves. There are two potential sources of fresh and brackish groundwater in subsea aquifers: (1) entrapped paleo-freshwater emplaced during glacial maxima, when sea levels were lower and continental shelves were exposed, and (2) modern fresh groundwater discharge from onshore aquifers (under current sea-level conditions). For freshwater to remain in subsea aquifers, a...
